5) ECO Cruise Control
The ECO cruise control system has nearly same functions with the auto cruise control system. It is an
automatic speed control system that maintains a desired driving speed without using the accelerator
pedal.
ECO cruise driving mode
The engine ECU controls the sharp acceleration and deceleration to improve the fuel economy.
The ECO cruise system is ready when pushing down the cruise control lever. At this moment, the
ECO indicator on the instrument cluster comes on.
The ECO cruise system operates when pulling up the cruise control lever.
To cancel the ECO cruise driving, push doen the cruise control lever. At this moment, the ECO
indicator on the instrument cluster goes off and the auto cruise starts to operate. -

6) Normal Cancellation of the Cruise Control
The cruise control system will be canceled when one or more items of the following conditions are
applied;
When the brake pedal is depressed.
When the cruising speed is downed less than 38 km/h.
When pushing the ON-OFF switch of the cruise control lever.
When ESP is activated.
When applying the parking brake when driving.
When using the clutch in order to shift (M/T only).
And the cruise control system can be operated again in driving state. 1.

Keep the main cruise control switch in the neutral position when not using the cruise control.

Do not move the shift lever to Neutral position while driving with the cruise control turned on.
Otherwise, it may result in system malfunction or accidents.
Always be prepared to use the brake or accelerator pedal for safe driving while the cruise control
system is running.
The actual speed can be different from the set speed momentarily when driving on a uphill or
downhill. So, it is recommended to disable the cruise control function on a uphill or downhill. hen
driving on a steep hill use the engine brake and foot brake properly to protect the vehicle system
and for a safe driving.
Ensure that the safe distance is maintained and use the brake pedal if needed. 1.

(1) Abnormal Cancellation of the Cruise Control
Sharp acceleration or deceleration
- 50 km/h faster than set speed
- 25 km/h faster than set speed for one minute
- 70 km/h slower than set speed
- 65 km/h slower than set speed for 3 minutes
When the cruise control lever is faulty.
When the brake switch and the brake light switch input signal are implausible. 1.
2.
3.
When the cruise control function is cancelled abnormally or intermittent problems occur, stop the vehicle
and turn off the ignition switch and remove the key to reset the system. After a while, turn on the ignition
switch again to operate the cruise control system.
